SHUTTLE BOX MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 371,769, dated October 18, 1887.

I Application filed May 23, 1887. Serial No. 239,083. (No model.)

To aZZ whom it may concern.-

Be it known that we, CHARLES H. KNOWL TON and BENJAMIN F. MEYER, both citizens of the United States, and residents of Camden, New Jersey, have invented certain Improvements in Shuttle-Box Mechanism for Looms, of which the following is a specification.

Our invention relates to that class of looms in which the shuttle-box slide carries a boX- cylinder free to rotate thereon, an instance of such a loom being shown in Murklands patent, No. 97,106, November 23, 1859.

The object of our invention is to provide for the movement of the cylinder irrespective of the movement of the slide, so that greater variety in the introduction of the weft-threads is possible than with shuttle-box mechanism of this class as now constructed.

In the accompanying drawings, Figure 1 is a side view of sufficientof a loom to illustrate our invention, and Fig. 2 a frontview of part of the loom.

To suitable hearings in the side frames, 1, of the loom is adapted a shaft, 2, cranks 3 on the ends of said shaft being connected by rods 4 to the swinging lathe 5, to suitable bearings on which is adapted the slide 6, carrying some of the shuttle-boxes 7, and having bearings for the shaft 8 of the cylinder 9, which carries the remainder of said boxes. The shnttlcbox slide 6 is connected by a link, 10, to an arm, 11, having an anti-friction roller, 12, which is acted upon by a cam, 18, on the cam-shaft 14, said cam being so shaped as to impart the desired risingand falling movements to the shut tie-box slide. Usually the shuttle-box cylinder 9 has laterally-projecting pins, which engage with notches in the limbs of a forked arm hung to the lathe, so that as the cylinder rises and falls with the shuttle-box slide the engagement of its pins with one or other of these limbs will cause the turning of the cylinder, so as to bring the boxes of the same in line with the shuttlerace. It will be evident that by this arrangement two of the shuttle-boxes of the cylinder cannot be brought into line successively with the shuttle race, for the movement of the cylinder necessitates a move ment of the slide, and, supposing the top box of the cylinder to be in the plane of the shuttle-race, the movement of the slide necessary to effect a partial rotation of the cylinder will carry the top of the latter below the plane of the shuttle-race; hence the range or variety in the order of succession of the weftthreads is somewhat restricted. In order to overcome these objections we have devised mechanism for operating the shuttle-box cylinder independently of the movement of the slide, and this mechanism we will now proceed to describe.

On the outer end of the shaft 8 of the shuttie-box cylinder is a bevel-wheel, 15, which engages with abevel-pinion,18, the hub of which is confined vertically to, but is free to turn in, bearings 17, carried by a bracket, 18, secured to and moving with the shuttle box slide 6. To a central opening in the hub of the pinion 16 is adapted a shaft, 19, of square or other polygonal form in cross-section, so that while the pinion 16 is free to move vertically on said shaft it must partake of any rotary motion imparted thereto. The lower end of the shaftis stepped in a bracket, 20, seen red to one of the side bars of the lathe, and said lower portion of the shaft has a bevel-pinion, 21, which gears into a bevel-wheel, 22, on a shaft, 23, also adapted to a bearingin thebracket 20, theinner end of the shaft being provided with a disk, 24, having a series of inwardlyprojecting pins, 25. It will therefore be seen that any movementimparted to the disk 24 is trans mitted to the shuttle-box cylinder 9, irrespective of the vertical position to which said shuttie-box cylinder may have been adjusted, so that two or more of the boxes of the cylinder may be brought successively in line with the shuttlerace, there being no extended vertical movement of the shuttle-box slide during this operation. Thereshould, however, beaslight drop in the cylinder before the same is rotated, so that the box will clear the usual protectorbar, which occupies a position at the back of the shuttle-race, as shown by the dotted circle 39 in Fig. 1. This drop of the cylinder we effect by means of the depression 40 in the cam 13.

For determining the movement of the shuttie-box cylinder we use a forked arm, 26, the opposite limbs of which have notches 27, for engagement with the pins 25 of the disk 24; but as the'latter has no'vertical movement it becomes necessary to reciprocate the arm 26, this movement being effected byacam, 28, on the shaft 14:, acting through the medium of an arm, 29, rock-shaft 30, and arm 31.

In order to determine which of the limbs of the forked arm 26 shall engage with a pin of the disk 24, and thus govern the direction of rotation of the latter and of the shuttle-box cylinder, we use a dictating-lever having two arms, 32, and'a third arm, 33, the arms 32 being connected by cords 34 with the Jacquard apparatus of the loom, and the arm 33 being connected by a rod, 35, to the upper end of one of the limbs of the arm 26, so that by proper operation of the cords 34 the dictatinglever may be so adjusted as to throw either of the limbs of the arm 26 into engagement with a pin of the disk 24 or move the arm to an intermediate position, as shown in Fig. 1, in which position of the arm both of the limbs are free from engagement with the pins of the disk. A lever, 36, acted on by a spring, 37, serves to prevent accidental displacement of the dictating-lever from either of the positions to which it may have been adjusted.

We claim as our invention- 1. The combination of the lathe of the loom, the shnttle-box slide, a box-cylinder carried thereby, a disk carried by the lathe, a shaft extending from the disk to the cylinder, gearing connecting said shaft to the cylinder and disk, and means for operating the disk and moving the shuttle-box slide, all substantially as specified.

2. The combination of the lathe, its shuttlebox slide having a cylinder, a disk carried by.

the lathe and having projecting pins, a shaft extending from the disk to the cylinder, gearing connecting said shaft to the disk and cylinder, a forked and notched arm for engaging with the pins of the disk, mechanism for moving said forked and notched arm into and out of engagement with the pins, and means for reciprocating the arm and the shuttle-box slide, all substantially as specified.

V 3. The combination of thelathe, the shuttlebox slide andits cylinder, a shaft parallel with the line of movement of the shuttle-box slide, a pinion carried by the slide and free to move on said shaft, a gear-wheel connected with the cylinder and engaging with said pinion, and means for imparting movements of partial rotation in opposite directions to the shaft, all substantially as specified.

4. The combination of the lathe, theshuttlebox slide and its cylinder, means for rotating the latter independent of the movement of the slide, and a slide-operating cam, constructed as described, so as to permit a slight drop of the cylinder prior to the rotation of the same, as set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
